This thesis presents an improved approach of food production methods. Fish and crops are the main focus of food production. Both fish and crops food productions were developed using the combination of aquaculture and agriculture. The term or method related to this combination called aquaponics. Aquaponics system uses the same circulating water contain in the tank for fish and crops. The main purpose of this system is to facilitate water circulation. The water from the fish pond required to be pumped into the growbed tanks. The growbed tanks are essentially acted as a place where the waste of the fish will be filtered out. The residue of the fish can exist in the form of liquid or particles. The processor is the brain of any embedded system. CT-UNO from Adruino product was used as the microcontroller-based while Raspberry-pi board used as microprocessor-based system. Each board has its own powering system terminal and circuit connection. These two boards were connected to an input from sensor and output
for the valve and Wi-Fi communication. The sensors composed of water level, pH, DO, EC, Temp and ORP sensor. All these elements were the content that can optimizing production process. A water level sensor was used to check the maximum water in the growbed while the rest were used to record and data measurement from the fish tank water elements such as pH, NH3, DO, and temperature. The data read by the solution sensor was sent to the processor board through 12C connection. Data of level sensor operated by varying the resistance based on the water level. All these data were monitored
through wireless connection. Data can be analyzed from the recorded sensor which can be read several times if needed. Level sensor also can be categorize acted as switch for the valve that mount on the bottom of growbed tank. When the water reach the maximum level, water valve will open to flush the water from the growbed to the fish tank. This output water has been filtered by the crop and medium in the growbed. A water valve has an external power source that consist of power relay to open and close the water flow. By implementing this method, crops get all based requirement to grow up effectively and all in all, the entire system worked successfully and served the project objectives.
